Light pollution
Stars seem to disappear from the city skyline at night due to light pollution caused by artificial lights.
It is the excessive or less use of artificial light that disrupts the natural patterns of wildlife, disrupts human sleep, and conceals the stars in the sky.
It is because in the city skyline there is excessive use of artificial lights and there is not a portion left which is not encroached by artificial lights.
Hence, option d) light pollution is the correct answer.

3. Denature and decrease its activity
Changes in pH can affect the activity of enzymes. Enzymes have an optimal pH which they function most efficiently, and changes from this pH can cause denaturation of the enzyme. An important aspect of molecular biology is that structure means function. Denaturation affects structure of the enzyme and therefore, function. A pH that is too acidic or basic can disrupt the ionic and hydrogen bonds that maintain the 3D structure. This denaturation results in a loss of enzyme activity rather than increase.
